All of a sudden, I am getting duplicate reminders in my email inbox. All reminders come in twice at the same time, and I don't understand why. I could submit the email headers to you if this would help.
Please find the task(s) for which you receive these reminders, right-click on it, go to "Reminders" and check if they have one or two reminders set up. If they only have one, please forward such double-mail to firstname.lastname@example.org and we'll look into it.
Actually, there were two reminders set up! Thank you for pointing that out. Now I just wonder how this happened... I don't remember consciously setting two reminders. But so what, problem solved, thank you!
